PRIMARY BATTERY.

Application filed February 28, 1911.

Serial N 611,434;

' To all whom it may. concern:

Be it known that I, AUGUSTE L. SALTZMAN, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Primary Batteries, of which the following is a specification. My invention relates generally to improvements in primary or voltaio batteries, and more particularly to that class in which the ne ative electrode consists of a plate of oxid 0% copper, or other depolarizing agent, properly molded and agglomerated, and the positive electrode of which. consists of a plate or plates of zinc.

My invention includes improvements 011 the structure described in the patent to Eben G. Dodge, 894,487, granted July 28, 1908. D In primary batteries of the type described in this patent, both the positive and negative elements are supported by one frame or hanger including an inverted U- shaped member, channel-shaped in cross sec- ,25 tion, which is secured to the battery jar ,cover by a bolt and nut whereby the electrodes and their supporting frame or hanger may be easily removed as a unitary structure for any desired purpose such as cleaning or renewals. In batteries of this type. the bolt is provided with a Wedge-shaped head which is drawn into engagement with the walls of the hanger by the nut when. the electrodes and their supporting frame or hanger are secured in place to the jaicover.

however, the nut is removed from the bolt,

the latter is no longer hold in place in the hanger and is liable to drop out of place thereby causing inconvenience.

The object of my invention is to provide improved means for holding the bolt or other suspension means in place in the supporting fralneoriliaugcr or other support mg structure, When the electrodes and their supporting structure are removed from the jar cover.

Another object of my invention to provide a connection whereby a very efficient electrical and mechanical contact between the bolt or correspondingsupport and the supporting structure is obtained.

My invention consists further in the details of. constru tion and combination of lVhen,

part-s hereinafter more particularly described and claimed.

In the accompanying drawings which form a part of this specification and in Which like reference characters refer to like parts in the several vieWs,Figure 1 is a side elevation partly in section of a portion of a battery embodying one form of my in vention; Fig. 2 is an elevation of the structure shown in Fig. 1 at right angles thereto, some of'the parts being shown in sect-ion; Fig. 3 is a. bottom plan view of the upper portion of the supporting frame orhanger and the means for securing the supporting,

copper or copper plated iron or steel, theedges of said strip being turned up to such an extent as to lie fiat againstthe edges of the negative electrode plate 3. The plate 3 preferably of copper oxid. The cross section of the hanger 2 is channel-shaped as shown in Figs. 3, 4 and 5. The hanger 2 is preferably given the form-of an inverted U,. the two arms or depending portions of which hold the-edges of the negative plate 3. The said plate 3 fits into the channel of the hanger 2 and is heldiin said hanger by any suitable supporting means, as for example, by lips 2 formed, on the loivcr ends of the depending arms of the hanger. The plate 3 is further clamped in the hanger by a horizontal cross piece or bridging member 5 preferably of similar material and cross section to the hanger 2. the member 5 being secured at either end to thc'sidcs of the hanger by end projection 6 whiehe-xtends through openings 8 in th-ehanger and are bent into clau ing position against the outside of the hanger.

The zinc or positive electrode plates of the battery designated at 9 are securedto an insulating block or blocks 10 and to the bridging member 5 by a suitable bolt 11. Thus the ZlIlC plates are supported from the bridging member. and the battery plates and their supporting frame form a unitary structure adapted to be-supported from the jar (lover by a single belt or other suspen sion means.

i As a means for supporting the frame and thebattery plates from'the jar cover, I have used a suitable bolt 12 which is preferably screw threaded. The bolt 12 is provided with a wedge-shaped head 13. The hanger 2 which, as hereinbefore stated, is channel shaped in cross section, is provided with an opening 14 in the base of the channel. In assembling the parts, the bolt 12 is passed through the opening 14: so that the stem of the bolt 12 passes through the opening it and the wedge faces are in engagement with the walls of the channel shaped hanger 2. As clearly shbwn in Figs. 3 and 5, the Walls of the channel where they engage the bolt head are spread apart so as to lie in close contact with the wedge faces of the bolt. Immediately beyond the portion of the hanger engaged by the bolt, the divergence .of the walls of the channel is decreased so as tov form two wedge shaped portions 15 of uniform cross section extending a short distance on both sides of the bolt. From the portions 15, the walls of the hanger converge to their normal relative position.

Loosely mounted on the stem of the bolt 12 is a gripping member 16 preferably formed of sheet metal as shown in the drawings. This member is provided at its ends with downwardly turned projections 17, a

pair of these projections being formed on each end of the member. The opposing edges of the projections of each pair are inclined to each other, so as to form two narrow opposing faces adapted to firmly grip between them, the portions 1.5 of the hanger and to force the walls of the said hanger firmly into contact with the bolt head when the nut 18 mounted on the screw threaded portion of the bolt and engaging the upper face of the gripping member clamps the said hanger, gripping member, and bolt together.

19 are openings to facilitate adjustment of the nut. In order to firmly bind the walls of the channel to the bolt head and to'produce a bomplete fiat contact between the said walls and the bolt head, yielding tongues or projections 20 are bent down from the front and back edges of the gripping member intermediate the projections 17. These ton gues "or projections are preferably inclined ini -wardly toward each other; and their lower ends are adapted to engage the Walls of the member 2 and to press the same firmly against the bolt head.

By means of the above described construc .tion, an efficient mechanical and electrical connection. between the bolt and hanger obtained, and the bolt becomes a part of the unitary structure including the battery plates and their supporting frame. This structure may be attached to the battery jar cover by placing the stem of the bolt 12 through a hole 21 in the battery jar cover, and drawing the structure in place by means of a nut 22. The nut 23 serves to lock the nut 22 in place and coZipe-rate with it and the bolt 12 to form a binding post for the attachment of a field wire negative element of the battery. It is evident that if it is desired to detach the battery plates and their supporting frame from the battery jar cover, the bolt will beret'ained in place in,

the hanger, and ready for reattachment to the battery. 1

The modification shown in Fig. 5 resembles that shown in the remaining figures in all respects except that the projecting tongues 20 on the gripping member are omitted.

Having now described my invention, what I claim as new and desire to secure by Let pers Patent of the-United States is as folows:
